Go to "add Device" on Windows, then , select "I have a location where all drivers are present" ("select Disk...") and select "Drivers" on the Full Vista package (or another loaction which matches HP CM1015/1017 drivers)

Let Windows installing all data with windows update and with the location you provided

The printer should be found as "HP Color Laserjet CM1015_CM1017 MFP PS". At this stage the scanner doesn't work, you have to do the same operation for installing scanner.

Go to "add Device", select "Scanner" , then select the place whare all drivers are located. Normally when you select the good driver, Windows tells you: "installing scanner"...

Finally, We don't install any software from HP, we let windows finding good drivers, sometimes, we help him to find a driver. That's all .

So "HP Imaging", "HP resources Center" are not installed anymore, nevertheless, I've got a color printer which is working properly. The scanner works as well using the "Windows numerisation" tool

However, Windows did not recognize the scanner when I added new device. So I right-clicked on the printer which was easily recognized, selected properties and updated the scanner drivers which were marked with a yellow sign. You have to browse your computer to the Full Vista Package. At first, I showed the location of the drivers inside the folder and it wouldn't install them. Then I selected the whole Full Vista Package and windows was able to find the drivers.

Thanks for this, Lazeerider -- it was just the clue I needed after lots of time wasted in the "uninstall everything, reinstall and fail at HP SCAN, HP EWS, HP...CM1015" loop. My setup DID WORK on Win7, not sure what all I did to start, but after the printer and computer were turned off for a long weekend, it came back broken. No joy even with all 6 executables set to Vista SP2 compatibility mode and careful attention to the process.

What finally worked after the install failed at the "plug in USB" stage, was to go the device in the Devices and Printers view, select the properties for the 3 of 5 components that were broken, and browse to the top of the unpacked ZIP, as you said.
